Another thing I forgot to mention: the block saver will be pushed out toward the bottom by the oil pan rubber seal causing the bellhousing to block alignment to be off. You should notch out the area around it so the block saver sits flush against the engine block and not pushed away from it. That is the only way to make it fit correctly as the rubber oil pan seal probably sticks out by 3/8" or so at least that's my experience with every aftermarket bellhousing I've used.
